MicroRNAs (miRNAs) are a class of small RNAs (sRNAs) that repress gene expression via high complementary binding sites in target mRNAs (messenger RNAs). Many miRNAs are ancient. and their intricate integration into gene expression programs have been fundamental for plant life. controlling developmental programs and executing responses to biotic/abiotic cues. https://www.perfumetank.com/product-category/detailing/
